There is a popular saying that leeks, eggs, chicken, carp as “hairy things”. After surgery, patients generally can not eat hairy food, otherwise it will cause disease recurrence, or even aggravation. But this is an absolutely wrong concept, there is no “hairy food” in Western medicine. After surgery, patients need to eat a light diet, while increasing vegetables and other vitamins, or fiber-rich foods to increase intestinal peristalsis and promote fecal discharge. Leek as a plant food, eating after surgery can increase intestinal peristalsis, and with the patient to provide the necessary vitamins, leeks can accelerate intestinal peristalsis and promote intestinal discharge of feces, so patients can eat leeks after surgery, there is no “hairy” said.
